摘要： An agricultural harvester includes a plurality of controllable subsystems and a forward-looking crop sensor that detects a characteristic of the crop in front of the harvester. The forward-looking sensor generates a first sensor signal indicative of the detected characteristic. The harvester further includes a component sensor that detects a characteristic of a component of the agricultural harvesting machine and generates a second sensor signal indicative of the detected characteristic. Adaptation logic receives the first and second sensor signals and determines a sensor conversion factor intermittently during operation of the agricultural harvester. Recommendation logic receives the conversion factor and generates a recommendation to change operation of a controllable subsystem, based in part on the calculated conversion factor and a value received from the forward-looking crop sensor. A control system controls the controllable subsystem based on the generated recommendation.

摘要： Methods and apparatus to track a blade are disclosed. A disclosed example apparatus includes a blade that is pivotable, first and second optical targets operatively coupled to the blade, and a first camera for collecting first imaging data of the first optical target within a first field of view. The example apparatus also includes a second camera for collecting second imaging data of the second optical target within a second field of view. The example apparatus also includes a selector to select at least one of the first or second imaging data, and a processor to determine an orientation of the blade based on the selected imaging data.
